Look at some of the reviews on tech sites like engadget. The transformer and transformer prime are both listed as good tablets with the prime being the newest. Both have really good reviews. The Samsung galaxy tab 10.1 also gets good reviews. People here will offer good advice as well. I just bought a hp tablet for $200 as a refurbished unit, but if you are looking for a high quality tablet you will be in the $400-600 range. Mine is simply for playing around on during downtime at work. Good luck and happy shopping.

I would highly recommend the asus transformer prime tablet but there are a couple other good ones too. It really just depends on what type of tablet and options you are looking for and whether you prefer a 7 inch or 10 inch tablet? Here is the best asus transformer review ive seen
